I think about the absolute WORST place I have ever driven in has to be Boston. That place scared the hell out of me. Maybe it's changed now, because that was many years ago. But the drivers in Boston used the blinkers as a "get the hell out of my way" signal. If you saw someone in the right lane next to you put on his/her left turn signal indicating a lane change, it means he/she IS coming over, regardless of what you think about it. I guess everyone else there knew the drill, but I sure didn't!
